Citrix XenServer CTO, Simon Crosby, interviewed

The Syscon guys RSS me all the time so we will linkback to the guys with this post ;-)

Virtualization Journal: Starting at 35,000 ft…where does the Xen hypervisor fit in the virtualization universe?
Simon Crosby: The Xen hypervisor is the industry’s most strategic code base for virtualization. Why? First, it is a tiny, optimized, open source reference standard hypervisor for a wide range of CPU architectures, with extensive support for high performance virtualization-enhanced CPUs and I/O subsystems. Because it has multiple routes to market in any given year, the hardware manufacturers ensure that Xen has “first and best” support for the latest hardware, ensuring that it always leads the industry in scalability and performance. In addition:
  • It is collaboratively built by the industry’s leading IT vendors, led by Citrix and including Intel, AMD, IBM, HP, Novell, Red Hat, Sun, VA Linux and many others.
  • The Xen security architecture is contributed by the security community, including researchers, IBM’s secure hypervisor project, the NSA and DoD.
  • Xen is used in the world’s largest virtualization deployments, for example by Amazon, with a deployment of thousands of servers virtualized using Xen.
  • The Microsoft Hyper-V hypervisor is in fact an implementation of the Xen reference architecture, built by Microsoft, and compatible with Citrix XenServer.
Virtualization Journal: The first public release of Xen was made available in 2003, how long did it take for you and your Cambridge collaborators to get it to that stage?
Crosby: The Xen code base has been in development now for seven years. When we started XenSource, we had released Xen 2.5, and were working on Xen 3.0.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Linux, Linux : Get started with VMWare and Knoppix or Ubuntu Live CD!

Well everyone's talking about it now and you're wondering "what the heck is Linux?". So you've finally come face to face with yourself and say it loudly(errum..In your head first , please). I want to learn it! I admit it, I've been a fool! I hafta learn this kool OS! OK chill! You're faced with a challenge of all that installation crap. And boy, ask the veterans they've made lot's of money just installing Linux and installing Oracle on Linux was a big thing. And talking about setting about clusters was only for Big Boys and doing Oracle RAC setup was only for BEEEG BOYZ!!! Ok I can see you're already sleeping on my story. And Hey! Stop drooling on my shoulder! Wake up!!! You yell back at me " WHAT DO I HAFTA DO? WHERE I GOTTA KLIK? I Don't wanna fight with my wife over installing Linux at home? And my Microsoft Boss is angry because I made my colleagues so scared when I installed Linux at work? Ok Ok I get it. You want to learn it'...
